Shiro Pichu involves applying a thick layer of cotton wool soaked in warm medicated oil to the head. The oil is periodically replenished to ensure it remains warm throughout the treatment. This therapy is highly effective for addressing degenerative and painful conditions such as back pain, osteoarthritis, spondylitis, and various injuries. The medicated oil is applied to the head for approximately 45 minutes, providing therapeutic relief and enhancing overall well-being.
